OGG时延问题记录

1.抽取进程延时

2.过程时间分析脚本

[oracle@node2 dirdat]$ cat test01.sh 
#!/bin/bash
echo "sql before time is "`date`>> test.log
sqlplus / as sysdba <> test.log
while true
do
	echo `stat st000000033 |grep Modify` >>test.log
done

insert into test07 (BIGINT_FIELD, DOUBLE_FIELD, BOOLEAN_FIELD, TIMESTAMP_FIELD, STRING_FIELD, START_TIME)
values (1, 3, ‘‘, null, ‘‘, sysdate);
truncate table test07;


select * from test07
select * from ogg12t.test07;
truncate table ogg12t.test07;

select arr_time-start_time from ogg12t.test07;
